- Fixed Biased
Hand Wiring
- Each amp is hand wired on vulcanized fiber tag board insuring durability
- solid cloth covered wire like the original (as opposed to stranded plastic coated wire) -- a must for a vintage, sweet tone
- Outstanding wiring techniques for a neat and clean look, less hum and less noise
Cabinet
80 Watts (5F8-A)
Dimensions: 18 1/2 " (H) x 26 1/2" (W) x 10 1/2" (D)
40 Watts (5E8-A)
Dimensions: 20" (H) x 24 1/2" (W) x 10 1/2" (D)
- Finger jointed solid pine
- Strong, durable
- Great natural resonance
- Hand Varnished Airplane luggage stripped Linen ( the exact material used for the original tweeds) for a natural vintage looking and feel, durable, washable
Chassis
- High Grade Stainless steel, less magnetic interferences (LESS HUM, LESS NOISE) and rust proof
- High grade Stainless Steel screws
- High grade Stainless Steel aircraft locking nuts for less vibration
- Industrial quality glass filled tube sockets, no rattling noise like NOS style counterparts. Tubes can be inserted and removed thousand of times
- All grounds are done with 18 gauge stranded wire, translating in LESS HUM, LESS NOISE
Resistors
- High quality Carbon composition, important ones are usually NOS Allen Bradley or Riken Ohm (Made in Japan) high precision, gold plated copper leads.
- Each resistor individually measured before wiring to insure exacting tolerances
- Low noise
- High temperature tolerance
- Extreme reliability
- Warm sound -- unlike metal or carbon film resistors
Capacitors
- High quality paper in oil or Solen Fast (made in France) coupling & decoupling caps
- Sprague Electrolytic Sprague or CDE (made in USA) for filtering caps
- highest quality and durability
- High quality caps are a key ingredient to the vintage tone
- All caps are formed slowly with a variac for stability and less noise
Power Transformers (by Mercury Magnetics in California)
- Highest quality transformers made by Mercury Magnetics
- Hand wound, paper interleaved
- Period correct voltages -- no cold, harsh, high plate voltages
- Center tapped filament -- no heater hum
- Available in 220V / 240 V / 100 V
Output Transformers (by Mercury Magnetics in California)
- Highest quality transformers made by Mercury Magnetics
- Manufactured using the actual Triad engineering data
- Hand wound, paper interleaved on paper bobbins
- High efficiency
- Rich harmonics - astounding tone
- Built to last forever
- Tremendous bottom end, shimmering highs, a lot of headroom
Testing
- Every component (resistor, capacitor, pots, etc.) is tested before installation
- Every soldered connection is tested
- Voltage checkpoints are verified throughout the circuit
- I test every amplifier for a substantial amount of time (sometimes it's hard to stop playing ...) and listen for potential rattling, vibrations sweeping frequencies with an audio signal generator
Speakers
- Jensen reissue P12Q AlNiCo are standard on the 40 watt
- Jensen reissue P12N AlNiCo standard on 80 Watt
- Celestion, Eminence, Weber and other speakers are available upon request.
